INSPECTION

1. DOOR LATCH

1. Check the cable of the rod, door opener and door lock for deformation. When it is deformed, straighten it because failure operations may occur. When it is unrepairable, replace the front door latch and door lock actuator assembly.

2. Check the lever, rod and wire for smooth operation.

2. LOCK ACTUATOR (MODELS WITHOUT DOUBLE LOCK)

1. Disconnect the door lock actuator harness connector.

2. Connect the battery to door lock actuator terminals.

If defective, replace the front door latch and the door lock actuator assembly.

Terminal No.

3. LOCK ACTUATOR (MODELS WITH DOUBLE LOCK)

1. Disconnect the door lock actuator harness connector.

2. Connect the battery to door lock actuator terminals.

If defective, replace the front door latch and the door lock actuator assembly.
